WAGON-JACK.

SPECIFICATIOOIII1g part of Letters Patent No. 224,461, dated February1o, 1880.

. Application filed October 14, 1879.

To all whom t may concern:

Be it known that I, LEWIS MILLER, of Oil City, in the County of Venangoand State of Pennsylvania, have invented new and useful Im'provements inWagon-Jacks, of which the following is a sp'ecification.

My invention relates' to that class'of jacks.

which are made with a not0hed elevating-bar to rest on the ground at oneend and joined at the other end toafulcrum-bar through the. medium of anoperating-lever, by the move me'nt of which the notched bar, which, inuse, is placed beneath the axle to be lifted, is raised or lowered, asrequired.

My improvement particularly consists, in the construction of anelbow-lever,as hereinafter described, forked to embrace the ends of thefulcrum-bar and notched elevating-bar respectively, and having a socketfor the recep tion of a handle; also, in the combination of theaforesaid. socketed elbow-lever with a notched elevating-bar andaflcrhm-bar, as V hereinafter described.

' In the accompanying drawings, Figure 1 is a side elevation of the jackwith the notched bar lowered. Fig. 2.is a side elevation-With the saidbar elevated. Fig. 3 is -a perspective view of the forked andsocketedel-bow-lever detached. Fig. 4 is a side view of the jack packedfor transportation or storage.

A represents the lifting-bar, constructed with any desirable number ofstep's or notches, a a a, on either one of which the axle of a wagon orother Vehicle may rest. B is a fulcrum -bar.

C represents my improved elbowlever, constructed With two cheek-plats orforks, c c, the extremities of which are pivoted to the up per end ofthe n0tched bar A, and the centra-l elbow portions to the extremity ofthe fulcrumbar B. The free end of the double or forked elbow-lever isprovided with a socket, c,for

- the reception of a handle, D, which will thus be placed in positionwhen the jack is to be used, or may be removed when it is desired topack the entire jack in a small compass for transportation or storage,as illustrated in My invention constitutes a valuable improvement in theclass of jacks referred to, in

that it Combines extreme simplicity in construction and operation withgreat strength and durability, as well as convenence in use.

In operation, the jack being in the position shown in Fig. 1, thenotched barA is inserted until the proper step a engages beneath theaxle; The hand-lever D being then drawu down, the elbow-joint 0 isthrown into the position shown in Fg. 2, causing the arms.which connectthe ends of the bars A B to pass a little beyond a vertical position,and thus afford secure Support,after the manner usual with jacks of thisclass. 7

The bars A, B, and D are constructed of wood, and the*connectin gelbow-lever or jointpiece 0 of metal, preferabl y of malleable iron.

I am aware thatlifting-jacks have been con' structed with notchedsupporting-bars pivoted to the ends of levers mounted on suitableframes. This construction, therefo're, I do not claim.- Having thusdescribed my invention, the

following is what I clain.as new therein and desire to secure by LettersPatent:

The connecting-iron C, constructed with two elbow b ranches, c c, and 'asocket, o, in com bi nation with a notched bar, A, fulcrum-bar B, andhandle D, substantially as shown and described. A
